Friday Puzzles #21

So perhaps things have been getting a little too mathsy; and certainly I could do with a sudoku break. So, here are a couple of easy Heyawake puzzles, themed with a small number of numbered rooms. Obviously when you focus on just one of the rules of a puzzle, then you lose some of the richness and variety, and this is the case with these two puzzles. As such they are both pretty easy. Still, I hope they still prove to have at least some fun factor coming from their novelty value.

#026 Heyawake – rated easy

I am wondering whether it is possible to do a Heyawake puzzle with no numbered rooms at all – at this stage I’m sort of conjecturing that with enough fiddling about with thin rooms in the corners it ought to be doable…whether that translates into any sort of a fun solve we shall have to see.
